To a 0° C. mixture of lithium aluminum hydride (2.0 g, 53 mmol) in anhydrous THF (100 mL) was slowly added a solution of ethyl 2-ethylpyridine-3-carboxylate (4.8 g, 26.8 mmol) in anhydrous THF (30 mL). The reaction mixture was stirred at 0° C. for 1.5 hours. The reaction was quenched with 5 N NaOH. Water (200 mL) and EtOAc (200 mL) were added. The mixture was stirred for 30 minutes. The solid material was removed by filtration. The organic layer was recovered. The aqueous layer was extracted with EtOAc (2×100 mL). The combined organic extracts were dried over MgSO4, filtered, evaporated, and dried in vacuo, affording (2-ethylpyridin-3-yl)methanol (3.1 g, 84% yield), which was used without further purification.
